Ryle Manufacturing Company has been manufacturing custom oilfield sprockets for drawworks, mud pumps, rotary tables, compound chain boxes, and winches since the 1950s. We have thousands of drawings in house for these applications. Ryle has manufactured oilfield sprockets for most of the equipment builder’s machines in service today. If there is a sprocket drawing that we don’t have we can make a new drawing or reverse engineer your sprocket to manufacture for you. If you have a drawing for the sprocket you want built, just send it to us for a quick and accurate quotation. Call us today! 1-800-433-0960
